To all whom it may concern:

' terfere with the Be it known that l, BAYARD E. Taylor, a citizen of the United States, and a resi;

dent of the town of Oak Park, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Metal Trucks; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

Heretofore metal trucks constructed so as to be sufficiently strong and durable have been objectionable owing to the great weight of the same.

This invention relates to a metal truck wherein the elements comprise tubular members of relatively light weight assembled and connected together in a manner adording a very rigid and substantial construction, and at the same time obviating to a great extent sharp corners and projections which inproper handling of articles thereon.

It is an object of this invention to provide a metal truck wherein the sill members are constructed of a plurality of tubular melnlit is also an object of this invention to construct a truck having tubular sills and cross bars connecting the same, and with suitable tubular reinforcing members inserted within the sills to greatly increase .the strength and without material increasing lid the weight thereof.

It is also an object of this invention to provide a truck havin sills and cross bars welded thereto to a 0rd a substantially unitary construction.

It. is also an object of this invention to construct a truck frame of tubular members, the cross bars of which are welded to the sills thereof and are also dished inwardly ets, stirrups, and toe detachably conweight and few parts, and wherein the auxiliary attachments may be easily removed therefrom when desired.

The invention (in a preferred form) is hereinafter more fully described and defined in the accompanying drawings and specifica ion.

In the drawings, Figure 1, is a side elevatlon of a truck embodying my invention. Fig. 2, is a top plan view thereof partly broken away, and shown in section. Fig. 3, is a section taken on line 33 of Fig. 1. Fig. l, is a section taken on line ls-4 of Fig. 1. Fig. 5, is a fragmentary View shown partly in section illustrating the connection of a part of the auxiliary attachment applied to the truck frame. Fig. 6, is a section taken online 66 of Fig. 3. Fig. 7, is a section taken on line 77 of Fig. 6.

'As shown in the drawings, the truck comprises tubes or tubular sill members 1, which are rigidly spaced and connected together in proper relation by means of tubular cross bars 2, welded at their ends to said tubular members 1, to afiord a substantially unitary construction. As shown in the views on the drawings disclosing said sill members 1, in section, a tube or tubular reinforcing member 3, of elliptical cross section,.though not necessarily so, is shown inserted within each of said sill members 1, and extending therethrough to a suficient length to give the desired rigidity. Flat metal strips 4, are riveted to said cross bars 2, intermediate the side sills, and serve to support smaller articles upon the truck and prevent the same falling through the same, as well as serving as a tie between the cross bars to increase the rigidity of the frame. As shown more clearly in Fi s. 3 and 4, said cross bars may be slightly dished at the middle thereof intermediate said members 1. The rear ends of the side members are swaged so as to form handles 5, and a toe 6, is inserted in said sill members 1, at the front end thereof, and is maintained therein by bolts 7. Wheel axle brackets 8, each having a relatively long concave upper portion 9, which receives the side sill members 11, therein, are secured to said sill members by means of said bolts 7, at one end thereof, together with other bolts 10, also extending through said tubular sill members. All. axle 11, extends through said brackets and mounted thereon are suitable g-wheels 12. A supporting rest or stirrup 13, is secured to said sill members one on each thereof at the rear of the truck frame by means of bolts 14, extending therethrough and each of said rests 13, is braced by a connecting member 15, which is also bolted to said end cross bar 2.

It is obvious from the description that the device consists of a relatively few number of parts, and inasmuch as the side sills and cross bars are welded together, the truck frame is substantially a one piece or unitary construction. When a load is upon the truck a transverse bending stress is applied to the side sill members, and inasmuch as the resisting moment afforded by said side sill members is directly dependent u on the depth of cross section of the same, side sills of much greater strength and relatively light weight are afforded by inserting the tubular elliptical members 3, within the circular tubular members 1, although of course the particular configuration of such tubular members may be varied. The wheel axle brackets, the supporting rests or stirrups, and the toe of the device, may be readily re moved from the truck frame by merely loosening the attaching bolts therefor.

stantially unitary truck frame comprising tubular side members, cross bars welded thereto, and reinforcing means within saidside members. 1 v

3. In a device of the class described, a tubular truck frame, the side sills and cross bars thereof welded to one another, and tubular reinforcing members inserted within the side sills of said frame.

4. In a device of the class described, a truck frame comprising tubular side members, cross bars secured thereto, a reinforcing element inserted within said tubular members, and a wheel axle bracket, supporting rest, and a toe, for the device detachably connected thereto.

5. In a device of the class described, a tubular truck frame comprising side sill members of circular cross section, a reinforcing tubular member of elliptical cross section inserted therethrough, tubular cross bars connecting said side sill members, and a wheel bracket and lifting toe secured to said frame.

6. In a device of the class described, a truck frame, tubular side sill members forming a part thereof, reinforcing means therein, a lifting toe insertible in the ends of said members, and bolts detachably retaining the same therein.

7 In a device of the class described, tubular side sill members, tubular reinforcing elements therein, and tubular cross bars connecting said side sill members.

8. In a device of the class described, side sill members, each comprising concentric tubes, tubular cross bars connecting the same, a lifting toe insertible in the ends of said members, a wheel bracket, a concave member on the upper portion thereof adapted to receive said side sill members therein, and bolts for connecting said wheel brackets, said side sill members and said lifting toe to one another.

9. In a device of the class described, side frame members comprising co-axial tubes, and cross-bars secured to said members.

10. In a truck of the class described, side sill members comprising co-axial tubes, cross-bars secured to said members, and wheel brackets, wheels, supportin rests, and a toe, for the truck associated with said members.

In testimony whereof I have hereunto subscribed my name in the presence of two subscribing witnesses.

BAYARD E. TAYLOR.
